I've received very abusive emails from one of my former students (adult education). She's accusing another former student from cheating in a recent exam, saying that he read verbatim from notes when he was doing a presentation. (This was an English exam for second language learners.) The exam rules don't exclude reading from notes though, obviously, it's best if students are as natural as possible. The complainant wants to do know what I'm going to do about it. The content and tone of her emails is very personal - directed at me but clearly about the other student.
Anyway, they were in a close relationship, living together (or are still - though hard to see how that could be the case) and I feel that I've been caught in the crossfire. I got back to her to say that I can't discuss another student with her for reasons of confidentiality.
She's taken it to my senior who is to speak to me soon. She's done this on, apparently, the grounds that I haven't done anything (obviously my polite but firm email reply wasn't good enough). There was no cheating - only a nervous student who used his notes as a prop where a more confident student wouldn't have had to. The exam was conducted properly. Trouble is, my employer isn't known for backing teaching staff and I can't stand the thought of an investigation and this going any further. In fact, my employer is generally very unsupportive.
Thoughts, advice - please!
